BrainAmp

For stimulus presentation, we use 32" BOLD screen from Cambridge Research Systems at 3T, 7T as well as the mock scanner.

Most important specifications:

   Size: 32 inch
   Resolution: 1920 x 1080
   Refresh Rate: 100 or 120 Hz
   Normalized luminance = normalized DAC-value ^ 2.2792
   Absolute luminance (cd/m2) = 0.157 + 106.643*((DAC-value/255)^2.2792)

Create a normalized gamma table with: Linearized DAC-value = EXP(LOG(UNCORRECTED DAC-VALUE)/2.2792)
